Menstrual impurity was ritually treated identically to venereal disease impurity.

Evidence

This text is perfectly symmetrical with one concerning gonorrhea-provoked impurity in man. And the purifying sacrifice is identical in the two cases. Seven days after she has been purified of her flow, two turtledoves or two young pigeons have to be brought to the sacrificer, who offers them to the Eternal. — Simone de Beauvoir, The Second Sex, 333

Categorization

• QUESTION: Why would Leviticus treat menstruation and gonorrhea symmetrically? Beauvoir uses it to ground impurity in secretion/leakage from the body rather than in femaleness per se — worth chasing the implication that impurity is about uncontrolled bodily flow, not gender.
• XREF: connects to: Menstrual blood’s impurity derives from its link to feminine fertility, not the blood itself — Simone de Beauvoir, The Second Sex, 338; Menstrual blood was ambivalent in matriarchal societies—both destructive and beneficial.
